嘿，我只是尝试使用非常基本的c ++程序将.reg文件合并到我的注册表中。
代码如下：
#include <iostream>
#include <iomanip>
#include <string>
#include <fstream>
#include <stdlib.h>
#include <cstdlib>
#include <stdio.h>
#include <windows.h>
using namespace std;
int main()
{
string file = "regedit.exe new.reg";
const char* ctv = file.c_str();
system(ctv);
system("PAUSE");
return 0;
}
我也尝试过使用这些系统命令：
ShellExecute(GetDesktopWindow(), "open", "new.reg", NULL, NULL, SW_SHOWNORMAL);
system("reg import new.reg");
system("regedit/s new.reg");
system("new.reg");
但他们的工作并没有好转。 非常有趣的是，如果我去Start，Run，并输入“regedit.exe new.reg” 注册表将更新;只是当我运行.exe程序时。 有什么想法吗？

结帐programmatically merge .reg file into win32 registry，另外import .reg files using win32 or other libraries。
请参阅http://msdn.microsoft.com/en-us/library/ms724889%28VS.85%29.aspx，这可能有所帮助。
RegLoadKey功能
在HKEY_USERS或下创建一个子项 HKEY_LOCAL_MACHINE并加载数据 从指定的注册表配置单元进入 那个子项。
备份或恢复的应用程序 系统状态包括系统文件 和注册表配置单元应该使用 卷影复制服务代替 注册表功能。
仅供参考，以下是处理导入的链接开源项目的代码：
